Abstract
OBJECTIVE:: We assessed the relationships between four circulating acute phase proteins and the circulating and adipose tissue levels of three adipocytokines. SUBJECTS:: In all, 15 nondiabetic obese women with a body mass index (BMI) above 32 kg/m2 were investigated. METHOD:: Circulating concentrations of C-reactive protein (CRP), alpha 1 acid glycoprotein (AAG), fibrinogen, alpha 1 antitrypsin and both circulating and adipose tissue levels of interleukin (IL)-6, tumor necrosis factor (TNF)α and leptin were measured by either nephelometry or enzyme-linked immunosorbent assay. RESULTS:: We found a strong positive correlation between both circulating and adipose tissue levels of IL-6, TNFα and leptin and serum CRP levels. All these adipose tissue adipocytokines were also positively correlated with serum AAG levels. These correlations disappeared when adjusted for fat mass, suggesting that the relationship observed was dependent on fat amount. CONCLUSION:: Our results indicate a strong relationship between adipocytokines and inflammatory markers, and suggest that cytokines secreted by adipose tissue in obese subjects could play a role in increased inflammatory proteins secretion by the liver.International Journal of Obesity (2004) 28, 993-997. doi:10.1038/sj.ijo.0802718 Published online 22 June 2004
